Is anecdotal evidence reliable in science?
Anecdotal evidence is none of those things. It’s one person’s experience, so it’s not representative. Depending on that individual’s perspective and biases, it may not be reliable. Its very nature as an anecdote means that collecting similar information under similar circumstances is not repeatable.

What is the best scientific evidence?
Systematic reviews draw on multiple randomised controlled trials to draw their conclusions, and also take into consideration the quality of the studies included. Reviews can help mitigate bias in individual studies and give us a more complete picture, making them the best form of evidence.
What’s the difference between science based and evidence-based?
Science-based – Parts or components of the program or method are based on Science. Research-based – Parts or components of the program or method are based on practices demonstrated effective through Research. Evidence-based – The entire program or method has been demonstrated through Research to be effective.
How do you know if research is scientific or research-based?
To be considered scientifically based, a research finding must be presented in a way that enables other researchers to reach the same results when they repeat the experiment. True scientific knowledge is public and open to challenge. It is held tentatively, subject to change based on contrary evidence.
